31 Claims.

This invention relates to tables of the refectory type in which the area of the table top may be enlarged by one or more leaves which are normally stored in inoperative position beneath the table top and are so connected. with the top that they may be disposed in operative position flush with the top and forming extensions thereof by simply pulling the leaves horizontally out from beneath the top.

One of the primary purposes of this invention is to provide mountings for the slidable leaves which will permit the leaves to be moved from inoperative to operative positions and vice versa with the exertion of but slight effort by simply 5" grasping the leaves and exerting a slight pull or push thereon and without the necessity of reaching under the table to manipulate any looking or fastening means.

Another purpose of the invention is to provide controlling means for the table leaves which will automatically bring the leaves into a position flush with the table top when the leaves are pulled out and which will automatically lower the leaves as they are slid into inoperative position so that they may be slid beneath the table top.

A further feature of my invention resides in the provision of means which automatically locks the leaves in their operative position against accidental displacement and automatically retains the leaves flush with and snugly against the table top so that the leaves form extensions of the top itself disposed in the same plane as the top and abutting the ends thereof, leaving no appreciable crack or opening between the top and its extensions.

Another object of the invention is to insure easy, smooth and accurate operation of the leaves by providing for adjustment of the leaf controlling mechanism so that compensation may be made when necessary for variation in the thickness of the table parts and for distortion of these parts which sometimes occurs through warping of the wood or from other causes. 45 A preferred embodiment of the invention is described in the following specification and illustrated in the accompanying drawings, referring to which:

Fig. i is a side elevation of a table constructed in accordance with this invention;

Fig. 2 is a horizontal sectional View on the line 22 of 1, looking upwardly beneath the table;

Fig. 3 is a vertical section on the line 3 3 of Fig. 2;

Fig. 4 is a vertical sectional view taken from the same position as Fig. 3 but with the two table leaves extended to operative position;

Fig. 5 is a vertical sectional view on the line 5-5 of Fig. 1;

Fig. 6 is an enlarged perspective of a locking 5 mechanism;

Fig. '7 is an enlarged perspective of a center bracket hereinafter described, and

Fig. 8 is a side elevation of the locking mechanism shown in Fig. 6.

Referring now to the drawings, there is shown a table having a top I, legs 2 and certain usual horizontal braces 3, 4, and 5 for imparting rigidity to the construction.

The top I is fastened to strips 5 which are in turn secured to the horizontal frame member 4, thus spacing the top upwardly from the frame members 4.

The normal length of the table top shown in Fig. 3 may be increased to the length shown in Fig. 4 by moving the leaves 6 and I from their inoperative position beneath the table top illustrated in Fig. 3 to the operative position at the ends of the topand flush therewith, as illustrated in Fig. 4. The leaf 6 is fixedly connected and supported by the outer ends of wooden bars 8 and 9, the inner endsof whichextend beneath the table top. The outer face of each bar is provided with. a longitudinally extending groove, which is designated 8' in the bar 8 and which terminates at the inner end of the bar in an offset portion 8", as best shown in Fig. 3. A bracket I I secured to and depending from the under side of the table top near the middle carries a laterally projecting pin or stud I2 which projects into the aforesaid groove in the bar. When the leaf is in its inoperative position beneath the top, as shown in Fig. 3, this pin I2 is disposed in the upper level 8' of the groove and when the leaf is extended into operative position, as illustrated in Fig. 4, the pin is disposed in the lower level 8" of the v groove so as to raise the bar to a higher level.

The bar 9 is similarly provided with a groove 9 of identical shape with the groove 8 in the bar 8 adapted to receive a similar pin I3 carried by a similar depending bracket I4. The level of both bars 8 and 9 and consequently the leaf 6 carried thereby is raised and lowered by the cooperative action of the offset grooves therein and the pins extending into said grooves.

To extend the leaf 6 to operative position the. user simply grasps the leaf 6 and draws it outwardly, causing the grooves 8' and 9 to slide along the stationary pins I2 and I3 as the bars 3 and. 9 move outwardly, and. as the lower portion 55 mechanism function exactly; alike.

8" of the groove 8' in the bar 8 and a corresponding lower groove portion (not shown) in the bar 9 are engaged by their respective pins I2 and IS the inner end of each bar will thereby be raised. At this time, a pin I5, secured by a bracket I5 to the side of the bar 8, will enter the slot I6 in a locking bracket I1 carried by the brace bar 5 and will ride up the lower cam surface of said slot until the operator, while lifting the leaf when its innermost edge I8 is free of the outer margin of the table top, causes this pin to move upwardly and back into the inner end 2i of the slot. The pin may then rest in the curved inner end 2I of the slot and thus hold the top of the table leaf flush with the surface of the table top. As the pin I 5 moves into the slot I6, it will strike a locking bar 22, push the same backwardly about the pivot 22 against the tension of the spring 23 until the pin' moves into the recess 2| whereupon the locking bar follows the pin and releasably locks it in an obvious manner. The construction of the locking bracket I1 is amply shown in Fig. 6, and its coaction with the pin I5 will be readily understood by reference to that figure. A stop 26 is provided in the form of a shoulder struck up from the bracket to limit the rotation of the bar 22 under the action of the spring. The bar or extension 9 is provided with a pin 25 (see Fig. 2) mounted on a bracket 25' which corresponds in location and function to the pin I5 carried by the bar 8. To cooperate with the pin 25 and the bar 9 another bracket I1, similar to the one shown in Fig. 6, is mounted in the position shown in Fig. 2 and functions as above described.

To return the leaf 6 to its concealed and inoperative position, the operator merely grasps the leaf, pulls it outwardly so that the pins I 5 and 25 push the locking bars 22 of the brackets I1 back, and this enables the operator to slide the pins downwardly and out of the slots I6, whereafter the operator can then push the table leaf underneath the table top.

The contour of the grooves 8 and 9' is such that in either extreme position of the table leaf the bars connected thereto will be held horizontally so that the surface of the table leaf will also maintain a horizontal position.

It will be observed that the table leaf 1 is provided with bars or extensions 26 and 21 constructed exactly like the bars8 and 9 and provided respectively with similar grooves 26' and 21'. The grooves in the bars 26 and 21 coact respectively with pins 28 and 29, which are in turn carried respectively by brackets 3| and 32 aflixed to the under side of the table top. Likewise, a locking pin 33 is carried by the bar 26, and. another similar pin 34 is carried by the bar 21 for locking the leaf 1 in extended operative position in cooperation with locking brackets I1 similar to the bracket I1 shown in Fig. 6.

In the embodiment herein shown, inasmuch as the pin 33 (see Fig. 2) protrudes far enough outwardly from the side of the bar 26 to engage the locking bracket I 1, it necessarily also would interfere with the inner end of the bar or extension 8, were it not for the fact that an elongated recess 33, shown in Fig. 2, is cut into the side of the bar 8 to allow these two bars, one carrying the protruding pin 33, to pass freely by each other. A

correspondingly similar groove 34 is cut into the face of the bar 9 to prevent interference by the pin 34.

In operation, both leaves and their associated One who desires to extend the leaf 6 from the position shown in Figs 1 or 3 into the position shown in Fig. 4 will grasp that leaf, pull it horizontally outwardly while the upper level of the grooves 8 and 9 slide past the stationary pins I2 and I3, and as the leaf approaches its fully extendedposition, the lower portionsof the grooves 8 and 9 ride up on the pins I2 and I3 respectively, lifting the inner ends of the bars while the operator manually lifts the leaf itself as he forces the pins I5 and 25 through the slots I6 into the locking recesses 2i of the brackets I1, momentarily forcing the locking bars 22 rearwardly but allowing them eventually to come forward and hold the pins l5 and 25 in locked position in the recesses 2 I. Since the inner end of the bar 8 and, likewise the inner end of the bar 9, both rest horizontally and substantially up against the under side of the table top, the leaf 6 will be maintained in horizontal position with its surface flush with the table surface.

The various parts of the mechanism will preferably be so proportioned as to position the adjacent edges of each leaf and the table top close to each other to minimize the aperture therebetween. Abutting contact between the opposed edges of the table top and leaf isassured by the pull of the springs exerted through their respective locking bars upon the pins projecting from the leaf supporting bars.

To release either leaf, the operator will merely 30 the brackets I 1, drop the leaf and push it under-- neath the table top.

The supporting bars for the leaves and their associated locking brackets I1 are widely spaced from the longitudinal center line of the table and thus afford a firm support for the extended leaves thereby precluding tilting.

It will be noted that when the leaves 6 and 1 are not in use, they are aligned with the table top and present a neat appearance. If desired, horizontal strips 36 and 31 (see Fig. 5) may be attached to the under side of the table top so that when the table is in shortened position the entire side edge of the table from end to end will have the same thickness and hence a uniform appearance. (See Fig. 1.)

It will be further noted that when the leaves are in their inoperative positions, they are virr tually concealed or at least scarcely noticeable, and furthermore neither dothey or the operating mechanism extend downwardly from the table so far as to make it inconvenient for persons to sit up close to the table.

As it may be desired to employ the same middle locking bracket I1 or the same center brackets such as II, I3, 3I or 32 on similar tables having tops and leaves of different thicknesses, these locking brackets and center brackets are provided with adjustments. These adjustments also are found useful in case a table leaf or the elongated bars which support it should warp. Referring to the locking bracket shown in Fig. 6, it will be noted that the bracket consists of a main angular body indicated by reference character I1 upon which is disposed a plate 4| provided with three screw holes 42, each of which registers with one of the elongated slots 43 in the body of the bracket. The bracket is secured to either of the braces 5 on the table by means ofscrews which extend through these holes and cooperating slots, it being obvious that whereas the plate M must remain stationary with respect to the table, the bracket I1 may be moved upwardly or downwardly within the range of the lengths of the slots Q3. 75

A lug 44 is struck up from the surface from the plate 4| leaving an aperture 45 through which extends another lug it struck up from the bracket H. The latter lug is provided with a slot 4? whose margins are crimped slightly inwardly to provide a bearing for a screw t8, provided above and below the lug with a shoulder 39 and screw head 5! respectively, the latter being provided with the usual kerf. The head and shoulder permit rotation of the screw but preclude longitudinal movement with respect to the lug 56. By rotating the screw which is threadedly engaged with the lug 44 the bracket I! will be moved upwardly or downwardly depending upon the direction of rotation, while plate M is retained in fixed position by the three screws which pass through the screw holes -52 into the braces 5 of the table. Manipulation of the screw 48 will therefore raise or lower the bracket I! so that the end 2! of its slot may be adjusted upwardly or downwardly to bring the top of any leaf perfectly flush with the top of the table when the leaf is at its extended position.

The pins l2, i3, 23 and 29 are also capable of adjustment into exact alignment with their grooves in their respective supporting bars so that these bars may slide freely and without binding when employed in connection with leaves of different thicknesses. With this end in view each of these pins is adjustably mounted on its depending supporting bracket. Since all of the brackets and pins are alike, the bracket l shown in Fig. I, may be considered as illustrative. Referring to this figure it will be observed that the bracket may be secured in fixed position to the under side of the table top by means of screws passing through the holes 52. The pin l2 carried by the bracket is formed to provide an annu-' lar shoulder 63 and a reduced threaded portion 62 projecting from said shoulder through an arcuate slot 53 in the bracket 1 l and also through an opening in the adjusting plate 58. The plate 58 is provided at one end with a tongue 59 adapted to be disposed in an opening 5 3 in the bracket H and about which the plate pivots and at its other end with a similar tongue 6! adapted to be positioned in any one of the three spaced openings 55, 56 or 5'! formed in the bracket H. It will be manifest that the position of the pin i2 with respect to the bracket may be raised or lowered depending upon in which of the three openings the tongue fil is seated. When the proper adjustment has been made which will align the pin with its groove in the supporting bar so as to insure free sliding movement of the bar, the parts are locked in adjusted position by a nut 64 threaded on to the reduced portion 62 of the pin so as to clamp the bracket l i and the plate 58 together between the shoulder 53 and the nut 64.

When the bracket is employed with a leaf of medium thickness, the plate 58 will normally be secured in the position shown in Fig. '7. If the center bracket is employed with a leaf of less than medium thickness, the tonguefi! may be inserted into the hole 55 thus slightly elevating the pin 12 and thus by its cooperation with the groove 8 in the bar 8 hold the bar a little bit higher. In such a case, the locking bracket I? would likewise be adjusted upwardly so that this thinner leaf would be held horizontally and with its surface exactly flush with the table top when extended.

The manner in which a leaf may actually warp will determine just how the adjustable features of the center brackets or looking brackets may be employedto correct for the warping. When once the warped condition was observed, it would be obvious as to which of the brackets associated with that leaf should be adjusted upwardly or downwardly to cope with the condition.

The constructions herein shown are capable of economical manufacture, are sturdy, so simple as to present little likelihood of maintenance troubles, and may readily be incorporated into a table.

It should be understood that the embodiment herein described has been selected for the purpose of illustrating a preferred form of the invention and that other embodiments may be devised within the spirit and scope of this invention as defined in the appended claims.
